IMPROVEMENT IN GOVERNORS.

Specification forming part of Letters Patent No. 203,699, dated May 14, 1878; application filed May 2, 1878.

a part of this specification.

This invention relates to that class of gov ernors which operate by drawing a sliding collar connected by cranks and rods to the governor-valve.

It consists in the construction, combination, and arrangement of the sliding collar, replacingspring, and device for regulating the tension of the latter, as hereinafter particularly set forth and claimed.

In the accompanying drawings, Figure. 1 represents a vertical section of my improved governor and its attachments, and Figs. 2 and 3 represent detail views of the parts thereof.

A designates the crank-shaft of an engine, turning in hearings on standards B B. Said shaft carries at one end a wheel, C, recessed at C C to allow and guide the vibration of governor-balls D D, formed on the outer ends of short elbowed arms (I d, which are pivoted to lugs 61 d on the back of said wheel. The rear or lower ends of said armsd are provided with knobs d which set into an annular groove, e, of a collar, E, which slides on shaft A. Said collar has also another annular groove, 0', which receives inwardlyextending pins or studs f f of a yoke, F, which is pivoted end to a lug on standard B, and

at its lower forms a bell-crank lever, with arod or arm, Gr, that is jointed to valve-rod H.

designates an expanding-spring, which is interposed between collar E and wheel C. J designates a set-screw, which binds, through the hub of said wheel, against shaft A, and by means of which said shaft may be adjusted and clamped, so as to regulate the resistance of said spring.

When the centrifugal action of the said governor-balls draws the said collar outward, the governor-valve H is raised, so as to close the port through which the steam passes from the boiler to the cylinder.

The upward pressure of the steam against the valve-rod aids in closing the said steamports, and hence a high pressure tends to neutralize itself. Thus excessive rapidity of running is prevented and more equable action insured.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of double-grooved collar E with valve-operating yoke F, having pins or studs ff, spring I, and governor-balls D, provided with knobs or pins at for engaging with said collar, substantially as set forth.

2. The combination of shaft A, collar E, spring I, and wheel 0 with set-screw J, operating through the hub of said wheel against said shaft to adjust the tension of said spring, substantially as set forth.

In testimony that I claim the foregoing as my own 1 affix my signature in presence of two witnesses.

GEORGE EDWARD BANNER.
